MECI-IANISM FOR THREADING SHUTTLES.

Specification of Letters Patent.

To all whom it may concern Be it known that I, JUIIANNES GABLER, head foreman, subjectperor, residing at Altltircherstrasse, Millhausen, in the Province of Alsace-Lorraine, German Empire, have .invented certain new and useful Improvements in Mechanism for Threading Shuttles, otwhieh the following is a full, clean-and exact description.

This invention relates to an improved means for threading shuttles for looms having a side pirn changing arrangement.

In carrying the invention into effect a thread guide casing is inserted in the shuttle having a slot running in a direction lengthwise of the shuttle, tor the introduc tion of the weft and a tube placed at right angles to the slot, which tube is provided with a helical slot adjoining the first mentioned slot for the introduction of the weft into the tube. The outer orifice of the tube is disposed on one side near the bottom of the shuttle so that the weft is guided from the pirn down near the bottom of the shuttle. The object of thus guiding the wait in a tube having its orifice down near the bottom ol the shuttle and which has a helical slot, is to prevent the weft from sliding out of the threading arrangement after it has been threaded.

The drawing illustrates a form of the invcntion in which Figure 1 shows a top plan of the complete shuttle: Fig. 2 shows a side view of the shuttle, with the thread in the orifice of the tube: Fig. 3 is a top plan view of the thread device removed from the shuttle; Fig. d

shows a rear elevation of the threading device removed; Flg. 5 is a side elevation thereof; Fig. 6 is a bottom plan view ot the threading arrangement; Figs. 7 and S are perspective views oi the threading device ttlh'tili from the front and rear ;'tS} )Ctftl\'(l Y.

llie threading arrangement consists ot a thread "'Ultlt) casuw which is arran ed in a of the German En1-' recess of the shuttle and secured therein preterably by means of a pin 6 which extends transversely through the shnttle and municating with the slot (Z and which has its outer open end located on the side of the shuttle about midway its height. The tube 0 is provided with a helical slot g which communicates with the slot (Z. In threading the shuttle the thread 0 coming from the pirn is passed between cheeks a and 7 into and through the slot (Z and the helical slot g of the tube 0 of the threading arrangement, and is thus guided from the pirn down near the thereby secured against sliding out.

I claim as my invcntion:-

In a threading mcchanism for loom shuttles, the combination of a th. ding block consisting of a length-wiseslotted guide (as ing and a short lube fixed to said casing and extending in a direction at right angles to the slot of the same, said tube having a holi-- 'al slot of which the lllllilllt'O opening is on t e lower side of the shuttle block and tube and which extends diagonally upwardly and outwardly toward the delivery end ol said tube and adapted to be threaded by drawing the thread under and to the rear of said tube.
